rolaim. (Cl. 304-46) This inventionrelates to, scaffolds and moreparticularly to scaffolds having improved scaffold brackets:

An object'of this invention is to provide animproved scaffold andscafiold brackets for use with the improved scafiold winch in my PatentNo. 2,424,910.

Another object of this invention is to provide an improved bracket forscaffolds having hook eyes on the upper ends of the arms in which thewinch may be attached and a loop on one side for supporting a guardrail.

Still another object of this invention is to provide an improvedscalTold bracket which is light weight and compact in construction andin which the supporting side arms may be folded into the base of thebracket to provide for a compact package which may be readilytransported with a minimum of space.

With the above and other objects in view, my invention consists in thearrangement, combination and details of construction disclosed in thedrawings and specifications, and then more particularly pointed out inthe appended claim.

In the drawings,

Figure l is a front elevation, partly broken away, of a scaffoldconstructed according to an embodiment of my invention,

Figure 2 is a vertical section, partly broken away, taken on the line2-2 of Figure 1,

Figure 3 is a horizontal section taken on the line 3-3 of Figure 2,

Figure 4 is a vertical section through the bracket in the foldedposition,

Figure 5 is an enlarged detail plan view, partly broken away, of the endof the bracket in Figure 4,

Figure 6 is a vertical section, partly broken away, taken on the line 66of Figure 2.

Referring to the drawings, the numeral Ill designates generally ascaffold constructed according to an embodiment of this invention. Thescaffold III comprises floor planks I I supported between a pair ofbrackets I2 and a guard rail I 4 supported above the planks I I on thebrackets I2.

The brackets I2 are formed of a, pair of oppositely disposed invertedL-shaped strips of metal angle I5 spaced apart by a short cylindrical ortubular spacer I6. The angle members I5 are disposed in face abuttingrelation with one side I! of each member extending outwardly at theupper end to provide a fiat base on which the planks I I may besupported. Bolts I8 along the length of the members I 5 extend throughthe vertical arms I9 thereof and through the spacers I6 and arefixed inposition by nuts 29.

On the rear or outer end of the brackets I2 there is. providedasupportingrod 2| pivotally connected at their lower end between theangles I5. The rod 2| is substantially longer than one half the lengthof the angles I5 and is formed at its lower end with a loop 22 which isadapted to be closed loosely about the end spacer I6, whereby the rod 2|may pivot about the spacer I6 and in its folded position is adapted tolie between the angles I5. The upper end of the rod 2| is formed with aloop 24 in which a hook 25 beneath a winch 26 may be engaged in theraised or extended position of the rod 2|. A rectangular U -shaped loop21 is fixed on the outer side of the rod 2| near the upper end thereofand is adapted to support a guard rail I4. A small loop 28 is fixed onthe rod 2| intermediate the length thereof for supporting an auxiliaryguard cable when desired.

A shorter supporting rod 29 is pivotally connected to the front or innerend of the angles I5 and is formed with a loop 39 on its lower end forengaging loosely about the front spacer I6. The rod 29 is formed at itsupper end with a loop 3| in which the hook 25 depending from a winch 26may be engaged. The rod 29 is substantially shorter than one half thelength of the angles I5 so that the rods 2| and 29 may be enclosedbetween the angles I5 in their folded position. 7

On each end of the bracket I2 there is fixed an angle 32 having avertical side closing the space between the angles I5 which angles 32provide a stop for the rods 2| and 29 in their extended position toprevent the rods 2| and 29 from being pivoted beyond a vertical positionas shown in Figure 2.

For transporting this scaifold support I2 from place to place, the rods2| and 29 are folded inwardly to be enclosed within the space betweenthe angles I5 with only the loops 2'! and 25 extending above the outlineof the angles I5, thus providing a very compact and readily handledpackage, as shown in Figure 4.

In use as a scaffold the arms 2| and 29 are raised to a verticalposition and a pair of brackets I2 may be spaced at any suitabledistance apart below the planks II, thereby being adaptable to variouslengths of scaffold planks II. Hooks 25 secured to winches 26 which aredescribed in my copending application may be engaged in. the upper loops24 and 3| in the rods 2| and 29 respectively, for raising and loweringthe scaffold 10 by an operator on the scaffold. A guard rail l4 may beinstalled in the loops 21 and when desired a cable or rope may beengaged in the loops 28 as an auxiliary guard cable.

I do not mean to confine myself to the exact details of constructionherein disclosed, but claim all variations falling within the purview ofthe appended claim.

What I claim is:

A scafiold supporting bracket comprising a pair of elongated oppositelydisposed parallel extending angle members on which planks may besupported, means securing said angle members together in spaced apartrelation longitudinally thereof, a first supporting rod having a loopformed on one end loosely extending between said angle members at oneend of the latter, pivot means carried by said angle members extendingthrough said loop for rookably connecting said rod to said anglemembers, a second supporting rod having a loop formed on one endextending loosely between said angle members at the other end thereof,pivot means extending through the loop of said second supporting rod forrockably connecting said second rod to said angle members, and bent tabsformed on the opposite ends of said angle members closing the spacebetween the latter and engageable with the adjacent ones of saidsupporting rods for limiting the rocking of said rods away from saidangle members.
